[U-Boot] [PATCH] scripts: fix binutils-version.sh for 'as' without a package.

[Bill Pringlemeir]

Commit 73c25753 fixed the common issue that binutil packages (tool/organization
that packaged or built the bin-utils) are included in brackets and this may
falsely be recognized as a version.  However, some tools do not provide a
'package' and previously we add the 'Gnu assembler..' to the version.

Run a 2nd pass on the 'version_string' to strip off any leading characters when
a package is not provided in brackets.
